The SeaI/O-647U-OEM brings industrial-grade serial connectivity to embedded environments. Designed specifically for OEMs and system builders, this compact PCB integrates four RJ45 VersaCom ports that simultaneously support RS-232 and RS-485 signal sets. Configuration is purely external—no internal switches, jumpers, or shunts are needed.
Ideal for tight enclosures or space-constrained builds, the board is powered by a wide-range 9–30VDC input and comes with high-retention USB connectivity for reliable data transmission.
It includes an RS-485 passthrough for seamless expansion using SeaI/O N-series OEM boards, enabling versatile I/O capability like digital relays, analog inputs, and more. Whether in custom control systems, kiosks, or automation panels, the 647U-OEM delivers reliable, fast, and scalable serial integration.
